DETAILED DESCRIPTION

The following disclosure provides many different embodiments or example for implementing different features of the provided subject matter. Specific example of components and arrangements are described below. These are, of course, merely examples and are not intended to be limiting. In the present disclosure, reference to the formation of a first feature over or on a second feature in the description that follows may include embodiments in which the first and second features are formed in direct contact, and may also include embodiments in which additional features may be formed between the first and second features, such that the first and second features may not be in direct contact. Besides, the present disclosure may repeat reference numerals and/or letters in the various examples. This repetition is for simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed.

Embodiments of the present disclosure are discussed in detail below. It should be appreciated, however, that the present disclosure provides many applicable concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative and do not limit the scope of the disclosure.

FIG. 1 illustrates a cross-sectional view of a semiconductor device package 1 in accordance with some embodiments of the present disclosure. The semiconductor device package 1 includes substrates 10, 11, electronic components 12, 13, and 14, encapsulants 15, 16, 17, and a shielding layer 18.

Each of the substrates 10 and 11 may be, for example, an interposer, a printed circuit board, a lead frame, or other substrate types. Each of the substrates 10 and 11 may be, for example, a paper-based copper foil laminate, a composite copper foil laminate, or a polymer-impregnated glass-fiber-based copper foil laminate. Each of the substrates 10 and 11 may be, or may include, an interconnection structure, such as a redistribution layer (RDL) and/or a grounding element.

The substrate 10 has a surface 101 and a surface 102 opposite to the surface 101. The substrate 10 may include one or more conductive pads 10 p 1 in proximity to, adjacent to, or embedded in and exposed at the surface 101 of the substrate 10. The substrate 10 may include a solder resist (not shown) on the surface 101 of the substrate 10 to fully expose or to expose at least a portion of the conductive pads 10 p 1 for electrical connections. Electrical contacts 10 s (e.g., solder balls) are disposed on the conductive pads 10 p 1 and can provide electrical connections between the semiconductor device package 1 and external components (e.g., external circuits or circuit boards). In some embodiments, the electrical contact 10 s includes a controlled collapse chip connection (C4) bump, a ball grid array (BGA) or a land grid array (LGA).

The electronic component 12 is disposed on the surface 101 of the substrate 10 and electrically connected with the substrate 10 through a flip-chip technique (such as connected through an electrical contact 12 s), a wire bonding technique, or other suitable technique. The electronic component 12 may be a chip, a die including a semiconductor substrate, a semiconductor memory (e.g., a dynamic random-access memory (DRAM)), or the likes.

The substrate 11 has a surface 111 facing the surface 102 of the substrate 10 and a surface 112 opposite to the surface 111. The substrate 11 may include one or more conductive pads 11 p in proximity to, adjacent to, or embedded in and exposed at the surface 111 of the substrate 11. The substrate 11 may include a solder resist (not shown) on the surface 111 of the substrate 11 to fully expose or to expose at least a portion of the conductive pads 11 p for electrical connections. Electrical contacts 11 s (e.g., solder balls) are disposed on the conductive pads 11 p and can provide electrical connections between the substrate 11 and the substrate 10. In some embodiments, the electrical contact 11 s may include, for example, eutectic Sn/Pb, high-lead solder, lead-free solder, pure tin solder, or other types of solders. In some embodiments, the height (or the stand-off) of the electrical contact 11 s (i.e., the gap between the surface 111 and the surface 102) is from about 160 micrometers (μm) to about 180 μm.

In some embodiments, the substrate 11 may have a thickness from approximately 100 μm to approximately 160 μm, such as about 110 μm, about 120 μm, about 130 μm, about 140 μm, and about 150 μm. In some embodiments, the substrate 11 may have a relative thinner thickness so as to possess a qualified thermal conductivity. In some embodiments, the electronic component 13 can be inspected under a test (such as an active temperature control (ATC) test) to identify know good die (KGD) through the electrical contact 11 s on the substrate 11. However, the thickness of the substrate 11 may be designed depending on design specifications, and the present disclosure is not limited thereto.

The electronic component 13 is disposed on the surface 111 of the substrate 11 and electrically connected to the surface 111 of the substrate 11 through an electrical contact 13 s. In some embodiments, the electronic component 13 may be compression bonded and/or thermocompression bonded on the surface 111 of the substrate 11. In some embodiments, a reflow operation may be carried out for the electronic component 13. The electronic component 13 has a surface 132 (such as an active surface) facing the surface 111 of the substrate 11 and a surface 131 (such as a backside surface) opposite to the surface 132. In some embodiments, the electrical contact 13 s may include a micro bump, a C4 bump, a BGA or an LGA. In some embodiments, the electronic component 13 may be a chip, a die including a semiconductor substrate, a central processing unit (CPU), a graphics processing unit (GPU), an accelerated processing unit (APU), or the likes. The electronic component 13 may include one or more integrated circuit devices (such as active devices and/or passive devices) and one or more overlying interconnection structures therein. In some embodiments, the electronic component 13 may have fine-pitch input/output (I/O) connections. For example, the bump pitch of the electrical contact 13 s may be equal to or less than 100 μm, equal to or less than 75 μm, equal to or less than 60 μm, or equal to or less than 40 μm. For example, a gap between the surface 132 and the substrate 11 is equal to or less than 50 μm, 40 μm, 30 μm, or less.

The encapsulant 16 is disposed between the electronic component 13 and the substrate 11. The encapsulant 16 surrounds the electrical contact 13 s. In some embodiments, the encapsulant 16 may include an underfill. In some embodiments, the encapsulant 16 may include an epoxy resin, a molding compound (e.g., an epoxy molding compound or other molding compounds), a polyimide (PI), a phenolic compound or material, material including a silicone dispersed therein, or a combination thereof.

The encapsulant 15 is disposed on the surface 111 of the substrate 11 to cover and encapsulate the electronic component 13. The encapsulant 15 covers or encapsulates the encapsulant 16. The encapsulant 15 is in contact with the encapsulant 16. The encapsulant 15 also covers or encapsulates the electrical contact 11 s. In some embodiments, the electrical contact 11 s may be deformed under a reflow process (such as the operation illustrated in FIG. 5D and FIG. 5D′″), which may make the connection between the electrical contact 11 s and the conductive pad 10 p 2 fail and cause the substrate 11 to tilt (or out of position). The encapsulant 15 may be used to protect the electrical contact 11 s from being deformed, which can improve the reliability of the electrical contact 11 s.

In some embodiments, the encapsulant 15 may include, for example, one or more organic materials (e.g., a molding compound, bismaleimide triazine (BT), a PI, a polybenzoxazole (PBO), a solder resist, an Ajinomoto build-up film (ABF), a polypropylene (PP), an epoxy-based material, or a combination of two or more thereof), inorganic materials (e.g., silicon, a glass, a ceramic, quartz, or a combination of two or more thereof), liquid-film material(s) or dry-film material(s), or a combination of two or more thereof.

In some embodiments, the encapsulant 15 and the encapsulant 16 may have different materials. For example, the encapsulant 15 and the encapsulant 16 may have different kinds of materials. For example, the fillers of the encapsulant 15 and the encapsulant 16 may have different sizes. For example, the size of the fillers of the encapsulant 15 may be greater than that of the encapsulant 16. For example, the size of the fillers of the encapsulant 15 may be at least three times greater than that of the encapsulant 16. For example, the size of the fillers of the encapsulant 15 may range from about 30 μm to about 10 μm. For example, the size of the fillers of the encapsulant 16 may range from about 10 μm to about 1 μm.

The electronic component 14 is disposed on the surface 112 of the substrate 11 and electrically connected with the substrate 11 through a flip-chip technique, a wire bonding technique, or other suitable technique. In some embodiments, the electronic component 14 may be compression bonded and/or thermocompression bonded on the surface 112 of the substrate 11 through a solder ball. In some embodiments, a reflow operation may be carried out for the electronic component 14. The electronic component 14 may be a chip or a die including a semiconductor substrate, one or more integrated circuit devices and one or more overlying interconnection structures therein. The integrated circuit devices may include active devices such as transistors and/or passive devices such resistors, capacitors, inductors, or a combination thereof.

The encapsulant 17 is disposed on the surface 112 of the substrate 11 to cover and encapsulate the electronic component 14. In some embodiments, the encapsulant 17 may include material as described above for the encapsulant 15. In some embodiments, the encapsulant 17 and encapsulant 15 are formed in separate operations. In some embodiments, the encapsulant 17 and encapsulant 15 may have the same material. In some embodiments, the encapsulant 17 and encapsulant 15 may have different materials.

The shielding layer 18 is disposed on an external surface of the encapsulant 17 and covers the encapsulant 17, a lateral surface of the substrate 11 and a lateral surface of the substrate 10. The shielding layer 18 may be electrically connected to a grounding element of the substrate 10. In some embodiments, the shielding layer 18 is a conformal shield. In some embodiments, the shielding layer 18 is a conductive thin film and may include, for example, aluminum (Al), copper (Cu), chromium (Cr), tin (Sn), gold (Au), silver (Ag), nickel (Ni) or stainless steel, or a mixture, an alloy, or other combination thereof.

In some embodiments, the encapsulant 22 may include material different from the encapsulant 21.

An encapsulant 23 is disposed on the surface 111 of the substrate 11 and surrounds the encapsulant 22. In some embodiments, the encapsulant 23 also surrounds the electrical contact 11 s. In some embodiments, the encapsulant 23 is disposed on a periphery of the substrate 11. In some embodiments, the encapsulant 23 is disposed on a periphery of the substrate 10. In some embodiments, the encapsulant 23 is disposed on an outer edge of the substrate 11. In some embodiments, the encapsulant 23 is disposed on an outer edge of the substrate 10. For example, referring to top views of FIGS. 2B and 2C, the encapsulant 23 is disposed on a corner of the substrate 11. In FIG. 2B, the encapsulant 23 surrounds the electrical contact 11 s and the encapsulant 22. In FIG. 2B, the encapsulant 23 is spaced apart from the electrical contact 11 s. In some embodiments, the encapsulant 23 can provide structural support to the substrate 11 and prevent the substrate 11 from tilting under a reflow process (such as the operation illustrated in FIG. 6D and FIG. 6D′″).

In some embodiments, the encapsulant 23 may include material different from the encapsulant 22. For example, the encapsulant 23 and the encapsulant 22 may have different kinds of materials. For example, the encapsulant 23 and the encapsulant 22 may have different filler sizes.

In some embodiments, the electrical contact 11 s may be protected from a reflow process (such as the operation illustrated in FIG. 6D and FIG. 6D′″) by the encapsulant 23. In some embodiments, the encapsulant 23 improves the reliability of the electrical contact 11 s.

At least some of these figures have been simplified to better understand the aspects of the present disclosure.

Referring to FIG. 5A, a substrate 11 is provided. An electronic component 13 is disposed on a surface 111 of the substrate 11 and electrically connected with the substrate 11 through an electrical contact 13 s. In some embodiments, the electrical contact 13 s may be formed by using an evaporation operation, an electrolytic plating operation, an electroless plating operation, a ball drop operation, or a screen printing operation. In some embodiments, the electronic component 13 may be compression bonded and/or thermocompression bonded to the substrate 11. In some embodiments, the electronic component 13 may be reflowed. An encapsulant 16 (such as an underfill) is disposed between the electronic component 13 and the substrate 11 to surround the electrical contact 13 s.

A conductive pad 11 p is formed over the surface 111 of the substrate 11. In some embodiments, the conductive pad 11 p may be formed by physical vapor deposition (PVD), chemical vapor deposition (CVD), electrolytic plating, electroless plating, or other suitable metal deposition process. An electrical contact 11 s is mounted on the conductive pad 11 p and may be reflowed. In some embodiments, the top surface of the electrical contact 11 s is higher than or equal to the top surface of the electronic component 13.

Referring to FIG. 5B, a singulation is performed to separate out individual structures in FIG. 5A. That is, the singulation is performed through the saw streets or scribes of the substrate 11. The singulation may be performed, for example, by using a dicing saw, laser, or other appropriate cutting technique.

Referring to FIG. 5C, the individual structures in FIG. 5B are flipped and disposed on a substrate 10. In some embodiments, the substrate 11 may be compression bonded and/or thermocompression bonded to the substrate 10.

In some comparative embodiments, the structure (such as an interposer strip) of FIG. 5A may be flipped and disposed on the substrate 10 without being singulated. However, the stress from the interposer strip may cause warpage issue. By singulating the interposer strip and then disposed individual interposer on the substrate 10, the warpage issue can be solved.

An encapsulant 15 is disposed on the substrate 10 to cover the substrate 11. In some embodiments, the encapsulant 15 may be formed by, for a paste printing, compressive molding, transfer molding, liquid encapsulant molding, vacuum lamination, spin coating, or other suitable applicators. In some embodiments, a planarization operation (such as chemical mechanical planarization (CMP), an etching process, or laser direct ablation (LDA)) may be performed to planarize the encapsulant 15 and expose the surface 112 of the substrate 11.

Referring to FIG. 5D, an electronic component 14 is disposed on the surface 112 of the substrate 11 and electrically connected with the substrate 11. In some embodiments, the electronic component 14 may be compression bonded and/or thermocompression bonded to the substrate 11. In some embodiments, the electronic component 14 may be reflowed. In some embodiments, as mentioned, the encapsulant 15 may protect the electrical contact 11 s and improves the reliability of the electrical contact 11 s. An encapsulant 17 is disposed to cover the electronic component 14. In some embodiments, the encapsulant 17 and encapsulant 15 are formed in separated operations. In some embodiments, the encapsulant 17 and encapsulant 15 may choose to have different materials.

In some embodiments, after the operation of FIG. 5B and before the operation of FIG. 5C, the individual structure in FIG. 5B can be inspected under a test (such as an ATC test) to identify KGD of the electronic component 13 through the electrical contact 11 s on the substrate 11.

Alternatively, after the operation of FIG. 5C and before the operation of FIG. 5D, the structure in FIG. 5C can be inspected under a test (such as an ATC test) to identify KGD of the electronic component 13 through the electrical contact 10 p 1 on the substrate 10.

In some embodiments, the ATC test may be conducted after the operation of FIG. 5D. However, scrapping the failed structure after the operation of FIG. 5D would decrease the yield rate and increase the manufacturing cost. By conducting the ATC test prior to the operation of FIG. 5D, such issues can be solved. For example, the identification of KGD of the electronic component 13 can be conducted before mounting the electronic component 14 on the substrate 11.

Referring to FIG. 5E, a singulation is performed to separate out individual structures in FIG. 5D. That is, the singulation is performed through the saw streets or scribes of the substrate 10.

Referring to FIG. 5F, a shielding layer 18 is disposed on an external surface of the encapsulant 17 and covers the encapsulant 17, a lateral surface of the substrate 11, and a lateral surface of the substrate 10. The shielding layer 18 may be formed by, for example, a plating process.

Referring to FIG. 5G, an electronic component 12 may be disposed on a surface 101 of the substrate 10 and electrically connected with the substrate 10. Electrical contact 10 s may be disposed on the surface 101 of the substrate 10 to provide electrical connections to external components. The final structure obtained from the operations of FIG. 5A, FIG. 5B, FIG. 5C, FIG. 5D, FIG. 5E, FIG. 5F, and FIG. 5G may be similar to the semiconductor device package 1 of FIG. 1.

In some embodiments, the operation of FIG. 5D may be replaced with the operations of FIG. 5D′, FIG. 5D″, and FIG. 5D′″.

FIG. 5D′, FIG. 5D″, and FIG. 5D′″ are cross-sectional views of a semiconductor device package at various stages of fabrication, in accordance with some embodiments of the present disclosure. At least some of these figures have been simplified to better understand the aspects of the present disclosure.

Referring to FIG. 5D′, after the operation of FIG. 5C (in which the individual structures in FIG. 5B are flipped and disposed on the substrate 10), a singulation is performed to separate out individual structures in FIG. 5C. That is, the singulation is performed through the saw streets or scribes of the substrate 10.

Referring to FIG. 5D″, the individual structures in FIG. 5D′ is disposed on a carrier 51 for physical support. In some embodiments, the carrier 51 may be replaced with a double-sided tape, a thermal release layer, a UV release layer, or another appropriate interface layer.

Referring to FIG. 5D′″, the electronic component 14 is disposed on the surface 112 of the substrate 11 and electrically connected with the substrate 11. The encapsulant 17 is disposed to cover the electronic component 14.

In some embodiments, after the operation of FIG. 5D′ and before the operation of FIG. 5D′″, the individual structure in FIG. 5D′ can be inspected under a test (such as an ATC test) to identify KGD of the electronic component 13 through the electrical contact 10 p 1 on the substrate 10.

After removing the carrier 51 from the encapsulant 17 and singulating the structure in FIG. 5D′″, the process may proceed to the operation of FIG. 5E.
